feat(multiphase): Add a way back from a margin without a power cycle

Browse Source 
blanton_multiphase_margin.sh gains 'normal', which returns all 38 rails
to their nominal set point from tools/Multiphase_Normal.txt. Same rails,
same per-rail reporting, same -u 0|1|all as the margin profiles.

Until now the tool could apply high3/low3/comboA/comboB and commit with
save, but had no way to undo. That left a power cycle as the only exit -
and worse, a save run while still margined would have written the offsets
into NVM, which a power cycle does not undo either.

Emitted commands were diffed against the source file: argv identical.

The nominal labels in the source carry extra text ("0.900V (nominal)",
"0.8V(nominal) , 0.8591V with load line"); the per-rail line prints just
the voltage so the column matches the other profiles. The load-line note
is kept as a comment above the data block, because reading 0.859 V back
from TH6_CORE after 'normal' looks like a failed write and is not one.

Script A -> V1.1.7.
